This project is a command-line utility designed for secure, content-addressable data archiving. It functions as an encrypted backup tool that stores data as deduplicated chunks, ensuring that every piece of information is identified by a cryptographic hash to maintain integrity across all backups. By applying strong encryption and message authentication codes to both data and metadata, the software prevents unauthorized access and detects potential tampering.
The tool distinguishes itself through a backend-agnostic storage abstraction that allows users to maintain repositories across diverse environments, including local filesystems, network-attached storage, and various cloud object storage providers. It optimizes storage efficiency and network performance by aggregating small data chunks into structured pack files and utilizing index-based metadata lookups. To further improve performance, the system maintains a local cache of repository indexes, which accelerates search operations and reduces latency during backup analysis.
Beyond its core storage capabilities, the software supports automated backup orchestration and disaster recovery planning through versioned snapshots. It provides a comprehensive set of management tools for inspecting repository objects and configuring secure connections to remote backends via standard protocols. The software is distributed as a portable binary, with support for installation through native package managers, containerized execution, and cross-compilation from source.
